导航使用手势滑动pop消失 ios

最佳处理方式

可以不看下面的了

-(void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated];
    [self.navigationController setNavigationBarHidden:YES animated:animated];
}


-(void)viewWillDisappear:(BOOL)animated{
    [super viewWillDisappear:animated];
    [self.navigationController setNavigationBarHidden:NO animated:animated];
}

 

如果用下面的，就会有bug

-(void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated];
    self.navigationController.navigationBar.hidden = YES;
}


-(void)viewWillDisappear:(BOOL)animated{
    [super viewWillDisappear:animated];
    self.navigationController.navigationBar.hidden = NO;
}

 

用最上面的解决方案后，

如果从无导航的A页面pop到无导航的B页面，会闪白条，可以从B的页面消失时，判断如果是A类就不显示导航了

 

-(void)viewWillDisappear:(BOOL)animated{
    [super viewWillDisappear:animated];
    if ([self.navigationController.viewControllers.lastObject isKindOfClass:[OpenUpRoomsDetailsVC class]]) {
        [self.navigationController setNavigationBarHidden:YES animated:animated];
    } else {
        //如果从无导航的页面跳到无导航的页面，pop时用下面的方法会闪白条
        [self.navigationController setNavigationBarHidden:NO animated:animated];
    }

}
